Prusa XL nozzle brush wipers

Inspired by other great wipers (espetially https://www.printables.com/model/644817-prusa-xl-series-front-nozzle-scrubber-including-g-). I decided to create my own.

Brushes at the front are fixed on frame (not the bed) so you can wipe any time (not just first layer). 5mm brushes with 2.4mm stem is used (https://www.alza.cz/hracky/shesto-rotacraft-stopkovy-drateny-kartac-mosazny-pr-5-mm-3-ks-d12520707.htm).

Brushes at the back are Karcher brass brushes (https://www.kaerchershop-schreiber.de/en/kaercher-round-brush-set-with-brass-bristles-sc.html). 2 sets are required.

M3 (flat head) screws and nuts are required. Metal or 3D printed 3030 T-nuts are required( printed for example: https://www.printables.com/model/134515-3030-m3-t-nut-drop-in-less-height-and-solid-sides-).

G-CODE for front brush:

G1 X330 Y-7 F24000
G1 X360 Y-7 F24000
G1 X330 Y-6.5 F24000

; end of nozzle wipe

* Recommend to put the G-Code in the printer settings in the “after layer change” and at the end of “tool change”.
